Magnetic Silicone

Magnetic Silicone is a composite of Iron Oxide and EcoFlex 00-30 Moulding Silicone.
Like the best things in life, this exploration came about by chance.
This material was discovered in the process of attempting to make soft iron cores for flexible electromagnets. The short video shows how different arrangements of the material reacts to permanent magnetic actuation.
